Components.

Virtual Lance Burner (VLB)Side wall and EBT mounted device for oxygen injection. Fuel is either gas or oil.

Virtual Lance Injector (VLI)VLB-type device achieving the shrouding effect without gas (only applicable for special furnace operations, e.g. hot metal).

Solid Material InjectorSide wall and EBT mounted device for injection of solid materials like carbon, lime and fines.

Optimising the electrical energy and adding chemical energy are major steps for maximum efficiency in EAF steel production.

The energy input concept by BSE represents a system family of sidewall and slag door input devices for chemical energy, current conducting electrode arms, hard- and soft-ware for measurement, control and analysis plus decades of experience in EAF steel production.

A winning combination that can help you to get the maximum performance out of your EAF and turn cold spots into ”hot” production figures.

Optimal foamy slag – one of the results of effective carbon injection.

Smart visualisation for quick access to each component of the system and control of total energy input.

BSE Energy Input SolutionsMaximise your output with efficient input!

Lance ManipulatorIn addition to the wall mounted devices, BSE has pioneered the slag door lancing technology with highly efficient consumable lances.

Electrode ArmsThe current conducting electrode arms increase active power in-put, furnace availability and overall productivity.

BSE Offgas System SolutionsClean and efficient!

Components.

Fluid Dynamic Model (FDM)Simulation of all heat and dust sources influencing the building ventilation by using a scaled Plexiglas® replica of the melt shop. The FDM, provided and performed by our subsidiary Bender Corporation, is an easy, accurate and economical tool to understand and improve the inside shop conditions.

Advantages.

● Improved dedusting efficiency in Am³/kWh.● Reduction of specific dedusting costs in Cost/Am³.● Less dust deposit in the ducts.● Better bag house utilisation by reduced and stable temperature.● Simplification of emission control.● HTQ as an economical solution for dioxin/furan reduction.● Lower pressure drop in the DEC duct.● Most economic analysing tools for improvement of building ventilation with FDM and optimisation of component details with CFD.

Computational FluidDynamics (CFD)Investigation with the aid of computer modelling to look into details of critical items and optimisation of mixing and distribution, pressure drop and local exhaust hoods. The Computational Fluid Dynamic guarantees a smooth enginee-ring process and highest per-formance of the designed dedusting systems.

Efficient Dedusting Control (EDC)Smart control and visualisation of the entire offgas system. The EDC collects realtime infor-mation of all key components, analyses it and anticipates accordingly.

HTQ valve rack with intelligent regulation of water flow ensuring a constant offgas outlet temperature and protection of the bag house against peak temperatures.

High TemperatureQuenching (HTQ)Rapid offgas cooling from direct furnace evacuation by injection of atomised water preventing de-novo synthesis of dioxin/furan. HTQ system consisting of a water spray chamber, a set of spray lances and a valve rack regulating the water amount ac-cording to process requirements.

Backed by the long standing know-how based on our own steel production, BSE provides analysing tools, engineering and key components for complete offgas systems that improve productivity and cost efficiency – along with strict compliance with environmental legislations.
